Constructor Detail

CallExpression

public CallExpression(SourceInfo info,
                      Expression expression,
                      Name target,
                      ExpressionList params,

Method Detail

clone

public Object clone()

Description copied from class: Node

Returns a clone of this Node and all its children. Immutable child objects are not necessarily cloned

Overrides:

clone in class Expression

isExceptionPossible

public boolean isExceptionPossible()

Description copied from class: Expression

Returns true if an exception can be thrown while executing this Expression. By default, returns true only if a type conversion could cause an exception.

Overrides:

isExceptionPossible in class Expression

getTarget

public Name getTarget()

setTarget

public void setTarget(Name target)

getExpression

public Expression getExpression()

setExpression

public void setExpression(Expression expression)

getParams

public ExpressionList getParams()

getInitializer

public Statement getInitializer()

Initializer is a section of code that executes before the substitution param. By default, it is null. If a CallExpression has a substitution param, a type checker may define an initializer.

getSubstitutionParam

public Block getSubstitutionParam()

isVoidPermitted

public boolean isVoidPermitted()

A CallExpression is permitted to return void only in certain cases. By default this method returns false.

setParams

public void setParams(ExpressionList params)

setInitializer

public void setInitializer(Statement stmt)

setSubstitutionParam

public void setSubstitutionParam(Block subParam)

setVoidPermitted

public void setVoidPermitted(boolean b)

isNullSafe

public boolean isNullSafe()

Specified by:

isNullSafe in interface NullSafe

setNullSafe

public void setNullSafe(boolean nullSafe)

Specified by:

setNullSafe in interface NullSafe
