getExtraDimensionsProperty
public final
SimplePropertyDescriptor getExtraDimensionsProperty()
- Returns structural property descriptor for the "extraDimensions" property
of this node.
-
-
Returns:
- the property descriptor
-
Since:
- 3.1
getInitializerProperty
public final
ChildPropertyDescriptor getInitializerProperty()
- Returns structural property descriptor for the "initializer" property
of this node.
-
-
Returns:
- the property descriptor
-
Since:
- 3.1
getNameProperty
public final
ChildPropertyDescriptor getNameProperty()
- Returns structural property descriptor for the "name" property
of this node.
-
-
Returns:
- the property descriptor
-
Since:
- 3.1
getName
public abstract
SimpleName getName()
- Returns the name of the variable declared in this variable declaration.
-
-
Returns:
- the variable name node
setName
public abstract void setName(
SimpleName variableName)
- Sets the name of the variable declared in this variable declaration
to the given name.
-
-
Parameters:
-
variableName - the new variable name
-
Throws:
-
IllegalArgumentException
- if:
- the node belongs to a different AST
- the node already has a parent
getExtraDimensions
public abstract 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.
-
-
Returns:
- the number of extra array dimensions
-
Since:
- 2.1
setExtraDimensions
public abstract void setExtraDimensions(int dimensions)
- 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.
-
-
Parameters:
-
dimensions - the number of array dimensions
-
Throws:
-
IllegalArgumentException
- if the number of dimensions is
negative -
Since:
- 2.1
getInitializer
public abstract
Expression getInitializer()
- Returns the initializer of this variable declaration, or
null if there is none.
-
-
Returns:
- the initializer expression node, or
null if
there is none
setInitializer
public abstract void setInitializer(
Expression initializer)
- Sets or clears the initializer of this variable declaration.
-
-
Parameters:
-
initializer - the initializer expression node, or null
if there is none
-
Throws:
-
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.
-
-
Returns:
- the binding, or
null if the binding cannot be
resolved
