Constructor Detail

AbstractMethodCallCheck

public AbstractMethodCallCheck()

Method Detail

getRelevantTokens

public Set<Integer> getRelevantTokens()

Description copied from class: AbstractAddonsCheck

The tokens which this check is interested in. Will be added to the tokens of the base class.

Specified by:

getRelevantTokens in class AbstractAddonsCheck

Returns:

the relevant tokens

isCheckActive

protected abstract boolean isCheckActive()

Determines if the check is configured to do anything at all.

Returns:

true if processing should be performed

isRelevantCall

protected abstract boolean isRelevantCall(@Nonnull
                     String pQualifier,
                     @Nonnull
                     String pMethodName)

Filter method which determines if the given method call is considered relevant.

Parameters:

pQualifier - the qualifier of the method call (for a call like Foo.Bar.call(), the qualifier is Foo.Bar)

pMethodName - the simple name of the called method

Returns:

indication of whether the call is relevant (true) or not (false)

visitMethodCall

protected abstract void visitMethodCall(@Nonnull
                   String pMethodName,
                   @Nonnull
                   DetailAST pMethodCallAst)

Visitor method called when a relevant method call is encountered. This method is called in addition to the other visitor methods.

Parameters:

pMethodName - the simple name of the called method

pMethodCallAst - AST of the call, useful for logging issues ( this is a METHOD_DEF, CTOR_CALL, or a SUPER_CTOR_CALL token)

getCurrentMethodName

@CheckForNull
public String getCurrentMethodName()

The current method name. "<init>" is used for constructors and instance initializers, and "<clinit>" is used for static initializers.

Returns:

the method name, or null if we are not inside a method, constructor, or initializer

beginTree

public void beginTree(DetailAST pRootAst)

Overrides:

beginTree in class AbstractAddonsCheck

visitToken

protected void visitToken(@Nullable
              String pBinaryClassName,
              @Nonnull
              DetailAST pAst)

Description copied from class: AbstractAddonsCheck

Called to process a token.

Overrides:

visitToken in class AbstractAddonsCheck

Parameters:

pBinaryClassName - the currently active binary class name

pAst - the token to process

leaveToken

protected void leaveToken(@Nullable
              String pBinaryClassName,
              @Nonnull
              DetailAST pAst)

Description copied from class: AbstractAddonsCheck

Called after all the child nodes have been processed.

Overrides:

leaveToken in class AbstractAddonsCheck

Parameters:

pBinaryClassName - the currently active binary class name

pAst - the token being completed
