  • Methodendetails

    • getNameProperty

      public final ChildPropertyDescriptor getNameProperty()
      Returns the structural property descriptor for the "name" property of this node (child type: SimpleName).
      Gibt zurück:
      the property descriptor

      3.1

    • getExtraDimensionsProperty

      public final SimplePropertyDescriptor getExtraDimensionsProperty()
      Veraltet.
      In JLS8 and later, use getExtraDimensions2Property() instead.
      Returns the structural property descriptor for the "extraDimensions" property of this node (type: Integer) (below JLS8 only).
      Gibt zurück:
      the property descriptor

    • getExtraDimensions2Property

      public final ChildListPropertyDescriptor getExtraDimensions2Property()
      Returns the structural property descriptor for the "extraDimensions" property of this node (element type: Dimension) (added in JLS8 API).
      Gibt zurück:
      the property descriptor

    • getInitializerProperty

      public final ChildPropertyDescriptor getInitializerProperty()
      Returns structural property descriptor for the "initializer" property of this node (child type: Expression).
      Gibt zurück:
      the property descriptor

    • getName

      public SimpleName getName()
      Returns the name of the variable declared in this variable declaration.
      Gibt zurück:
      the variable name node

    • setName

      public void setName(SimpleName variableName)
      Sets the name of the variable declared in this variable declaration to the given name.
      Parameter:
      variableName - the new variable name
      Löst aus:
      IllegalArgumentException - if:
      • the node belongs to a different AST
      • the node already has a parent

    • getExtraDimensions

      public int getExtraDimensions()
      Returns the number of extra array dimensions over and above the explicitly-specified type.

      For example, int x[][] has a type of int and two extra array dimensions; int[][] x has a type of int[][] and zero extra array dimensions. The two constructs have different ASTs, even though there are really syntactic variants of the same variable declaration.

      In the JLS8 API, this method is a convenience method that counts extraDimensions().

      Gibt zurück:
      the number of extra array dimensions

    • setExtraDimensions

      public void setExtraDimensions(int dimensions)
      Veraltet.
      In the JLS8 API, this method is replaced by extraDimensions() which contains a list of Dimension nodes.
      Sets the number of extra array dimensions over and above the explicitly-specified type.

      For example, int x[][] has a type of int and two extra array dimensions; int[][] x has a type of int[][] and zero extra array dimensions. The two constructs have different ASTs, even though there are really syntactic variants of the same variable declaration.

      Parameter:
      dimensions - the number of array dimensions
      Löst aus:
      IllegalArgumentException - if the number of dimensions is negative
      UnsupportedOperationException - if this operation is used in a JLS8 or later AST

    • extraDimensions

      public List extraDimensions()
      Returns the live ordered list of extra dimensions with optional annotations (added in JLS8 API).
      Gibt zurück:
      the live list of extra dimensions with optional annotations (element type: Dimension)
      Löst aus:
      UnsupportedOperationException - if this operation is used below JLS8

    • getInitializer

      public Expression getInitializer()
      Returns the initializer of this variable declaration, or null if there is none.
      Gibt zurück:
      the initializer expression node, or null if there is none

    • setInitializer

      public void setInitializer(Expression initializer)
      Sets or clears the initializer of this variable declaration.
      Parameter:
      initializer - the initializer expression node, or null if there is none
      Löst aus:
      IllegalArgumentException - if:
      • the node belongs to a different AST
      • the node already has a parent
      • a cycle in would be created

    • resolveBinding

      public IVariableBinding resolveBinding()
      Resolves and returns the binding for the variable declared in this variable declaration.

      Note that bindings are generally unavailable unless requested when the AST is being built.

      Gibt zurück:
      the binding, or null if the binding cannot be resolved
