Enclosing class:
GeometryFunction
public static final class GeometryFunction.GeometryValue<F extends GeometryFunction> extends Object implements ADQLOperand

    • getFeatureDescription

      public final LanguageFeature getFeatureDescription()
      Description copied from interface: ADQLObject
      Get the description of this ADQL's Language Feature.

      Note: Getting this description is generally only useful when discovery optional features so that determining if they are allowed to be used in ADQL queries.

      Specified by:
      getFeatureDescription in interface ADQLObject
      Returns:
      Description of this ADQL object as an ADQL's feature.

    • setColumn

      @Deprecated public final void setColumn(ADQLColumn col)
      Deprecated.
      Use setUnknownTypeValue(UnknownType) instead.

    • setGeometry

      public void setGeometry(F geometry)

    • setUnknownTypeValue

      public void setUnknownTypeValue(UnknownType val)
      Since:
      2.0

    • getValue

      public ADQLOperand getValue()

    • isColumn

      public boolean isColumn()

    • isNumeric

      public boolean isNumeric()
      Description copied from interface: ADQLOperand
      Tell whether this operand is numeric or not.
      Specified by:
      isNumeric in interface ADQLOperand
      Returns:
      true if this operand is numeric, false otherwise.

    • isString

      public boolean isString()
      Description copied from interface: ADQLOperand
      Tell whether this operand is a string or not.
      Specified by:
      isString in interface ADQLOperand
      Returns:
      true if this operand is a string, false otherwise.

    • getPosition

      public TextPosition getPosition()
      Description copied from interface: ADQLObject
      Gets the position of this object/token in the ADQL query.

      By default, no position should be set.

      Specified by:
      getPosition in interface ADQLObject
      Returns:
      Position of this ADQL item in the ADQL query, or NULL if not written originally in the query (for example, if added afterwards).

    • isGeometry

      public boolean isGeometry()
      Description copied from interface: ADQLOperand
      Tell whether this operand is a geometrical region or not.
      Specified by:
      isGeometry in interface ADQLOperand
      Returns:
      true if this operand is a geometry, false otherwise.

    • getCopy

      public ADQLObject getCopy() throws Exception
      Description copied from interface: ADQLObject
      Gets a (deep) copy of this ADQL object.
      Specified by:
      getCopy in interface ADQLObject
      Returns:
      The copy of this ADQL object.
      Throws:
      Exception - If there is any error during the copy.

    • getName

      public String getName()
      Description copied from interface: ADQLObject
      Gets the name of this object in ADQL.
      Specified by:
      getName in interface ADQLObject
      Returns:
      The name of this ADQL object.

    • adqlIterator

      public ADQLIterator adqlIterator()
      Description copied from interface: ADQLObject
      Gets an iterator on the intern ADQL objects.

      Note: The returned iterator is particularly used by a ISearchHandler extension to browse a whole ADQL tree.

      Specified by:
      adqlIterator in interface ADQLObject
      Returns:
      An ADQL objects iterator.

      Description copied from interface: ADQLObject
      Gets the ADQL expression of this object.
      Specified by:
      toADQL in interface ADQLObject
      Returns:
      The corresponding ADQL expression.
