```
public static QueryFirstRequest.Fields[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (QueryFirstRequest.Fields c : QueryFirstRequest.Fields.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static QueryFirstRequest.Fields valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getArrayDimensions
```
public UaArrayDimensions getArrayDimensions()
```
    Description copied from interface: FieldSpecification
    
    Returns ArrayDimensions of the field (or null if not known).
    
    Specified by:
    
    getArrayDimensions in interface FieldSpecification
  - getCompositeClass
```
public Class<?> getCompositeClass()
```
    Description copied from interface: FieldSpecification
    
    Returns the "non-array" version of type (the Class) of the field. For scalar values this is the same as FieldSpecification.getJavaClass(), for array fields this is the element type of the array.
    
    Specified by:
    
    getCompositeClass in interface FieldSpecification
  - getDataTypeId
```
public UaNodeId getDataTypeId()
```
    Description copied from interface: FieldSpecification
    
    Returns the DataType node's NodeId of the UA type of this field. For types read from a TypeDictionary this is a best-effort guess and might be null.
    
    Specified by:
    
    getDataTypeId in interface FieldSpecification
    
    Returns:
    
    DataTypeId of the field, can be null if unknown.
  - getDescription
```
public String getDescription()
```
    Description copied from interface: FieldSpecification
    
    Returns Description of the field. Can be null if not known.
    
    Specified by:
    
    getDescription in interface FieldSpecification
  - getEncodeTypeId
```
public UaNodeId getEncodeTypeId()
```
    Description copied from interface: FieldSpecification
    
    Mostly for internal use. For non-FieldSpecification.isAllowSubTypes() returns the same as FieldSpecification.getDataTypeId(). For AllowSubTypes fields returns UaDataTypeIds.Structure for Structure fields and UaDataTypeIds.BaseDataType for others (AllowSubTypes fields are binary-encoded as ExtensionObject or Variant, depending on the type).
    
    Specified by:
    
    getEncodeTypeId in interface FieldSpecification
  - getFieldIndex
```
public int getFieldIndex()
```
    Description copied from interface: FieldSpecification
    
    Returns a "field index" position of this field. Mostly intended for SDK internal use. The fields of a Structure can be thought as an Object[], this gives a suitable index (first field is 0, second is 1 and so on).
    
    Specified by:
    
    getFieldIndex in interface FieldSpecification
  - getJavaClass
```
public Class<?> getJavaClass()
```
    Description copied from interface: FieldSpecification
    
    Returns the java Class of the field. If the field is array type, then this Class object also is an array version, e.g. for a scalar Double field this returns Double.class, for 1-dim Double field Double[].class and for 2-dim Double[][].class and so on.
    
    Specified by:
    
    getJavaClass in interface FieldSpecification
  - getJavaClassDimensions
```
public int getJavaClassDimensions()
```
    Description copied from interface: FieldSpecification
    
    Returns the dimensions this field has. The return is the same as MultiDimensionArrayUtils.getClassDimensions(getJavaClass()). For non-scalar fields this return is equal to the FieldSpecification.getValueRank(), for scalar this returns 0.
    
    Specified by:
    
    getJavaClassDimensions in interface FieldSpecification
  - getMaxStringLength
```
public int getMaxStringLength()
```
    Description copied from interface: FieldSpecification
    
    Maximum length of a String this field can have (or 0 if not known or the field is not a String type). If an array applies to each element.
    
    Specified by:
    
    getMaxStringLength in interface FieldSpecification
  - getName
```
public String getName()
```
    Description copied from interface: FieldSpecification
    
    Returns the name of the field.
    
    Specified by:
    
    getName in interface FieldSpecification
  - getXmlName
```
public String getXmlName()
```
    Description copied from interface: FieldSpecification
    
    Internal. Application code shouldn't use this, but SDK may use this instead of FieldSpecification.getName() if more context is available, such as symbolic names in NodeSet documents. Returns same as FieldSpecification.getName() if there no such context.
    
    Specified by:
    
    getXmlName in interface FieldSpecification
  - getValueRank
```
public int getValueRank()
```
    Description copied from interface: FieldSpecification
    
    Returns the ValueRank defining the number of dimensions of the field. Either -1 (scalar) or a fixed number of dimensions (1+).
    
    Specified by:
    
    getValueRank in interface FieldSpecification
  - isAllowSubTypes
```
public boolean isAllowSubTypes()
```
    Description copied from interface: FieldSpecification
    
    Returns true if the field allows sub types to be set.
    
    Specified by:
    
    isAllowSubTypes in interface FieldSpecification
  - isArray
```
public boolean isArray()
```
    Description copied from interface: FieldSpecification
    
    Returns true if this field is an (potentially multidimensional) array. Returns false if it is a scalar.
    
    Specified by:
    
    isArray in interface FieldSpecification
  - isOptional
```
public boolean isOptional()
```
    Description copied from interface: FieldSpecification
    
    Returns true if the field is optional.
    
    Specified by:
    
    isOptional in interface FieldSpecification
