org.eclipse.jdt.core.dom.MethodInvocation

public class MethodInvocation
extends Expression
extends Expression

Method invocation expression AST node type. For JLS2:

 MethodInvocation:
     [ Expression . ] Identifier
         ( [ Expression { , Expression } ] )

For JLS3, type arguments are added:

 MethodInvocation:
     [ Expression . ]
         [ < Type { , Type } > ]
         Identifier ( [ Expression { , Expression } ] )

Since:: 2.0
Restriction:: This class is not intended to be instantiated by clients.

Since:: 3.0

Method Detail

propertyDescriptors

public static 
List propertyDescriptors(int apiLevel)

Returns a list of structural property descriptors for this node type. Clients must not modify the result.

Parameters:: apiLevel - the API level; one of the AST.JLS* constants
Returns:: a list of property descriptors (element type: StructuralPropertyDescriptor)
Since:: 3.0

getExpression

public 
Expression getExpression()

Returns the expression of this method invocation expression, or null if there is none.

Returns:: the expression node, or null if there is none

isResolvedTypeInferredFromExpectedType

public boolean isResolvedTypeInferredFromExpectedType()

Returns true if the resolved return type has been inferred from the assignment context (JLS3 15.12.2.8), false otherwise.

This information is available only when bindings are requested when the AST is being built

Returns:: true if the resolved return type has been inferred from the assignment context (JLS3 15.12.2.8), false otherwise
Since:: 3.3

setExpression

public void setExpression(
Expression expression)

Sets or clears the expression of this method invocation expression.

Parameters:

expression - the 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

typeArguments

public 
List typeArguments()

Returns the live ordered list of type arguments of this method invocation (added in JLS3 API).

Returns:: the live list of type arguments (element type: Type)
Throws:: UnsupportedOperationException - if this operation is used in a JLS2 AST
Since:: 3.1

getName

public 
SimpleName getName()

Returns the name of the method invoked in this expression.

Returns:: the method name node

setName

public void setName(
SimpleName name)

Sets the name of the method invoked in this expression to the given name.
