gololang.ir.MethodInvocation

public final class MethodInvocation
extends AbstractInvocation<MethodInvocation>

Represent a method invocation on an expression.

For instance golo code as

 foo()?: bar(42)
 

can be generated with:

 invoke("bar").nullSafe().withArgs(42).on(call("foo"))

Method Detail

invoke

public static MethodInvocation invoke(java.lang.String name)

self

protected MethodInvocation self()

Specified by:

self in class GoloElement<MethodInvocation>

isNullSafeGuarded

public boolean isNullSafeGuarded()

Checks if this invocation is null-safe.

I.e. if called with an elvis operator syntax (obj?: method())

nullSafe

public MethodInvocation nullSafe(boolean v)

Defines if the invocation is null-safe or not.

nullSafe

public MethodInvocation nullSafe()

Defines the invocation as null-safe.

on

public BinaryOperation on(java.lang.Object target)

Defines the receiver of the invocation.

withArgs

public MethodInvocation withArgs(java.lang.Object... args)

Defines the values of the arguments for this invocation.

This is a builder method.

This methods appends the arguments to the existing ones, so that it can be called multiple times to create the invocation incrementally. On the other hand, it is not idempotent.

Calls AbstractInvocation.withNamedArguments() if needed.

Overrides:

withArgs in class AbstractInvocation<MethodInvocation>

Parameters:

args - the arguments of the invocation. An argument can be any GoloElement, or are converted with ExpressionStatement.of(Object) otherwise, so that strings and primitives are automatically wrapped in a ConstantStatement.

Returns:

this invocation

See Also:

AbstractInvocation.withNamedArguments(), ExpressionStatement.of(Object)

accept

public void accept(GoloIrVisitor visitor)

Accept the visitor.

This method should only call the visitor visitXXXX method. The children of this node will be visited by the GoloElement.walk(GoloIrVisitor) method.

Specified by:

accept in class GoloElement<MethodInvocation>
