Method Detail

isContextFlagSet

protected final boolean isContextFlagSet(AbstractInvocationContext.ContextFlag flag)

Tests whether a context flag is set.

Parameters:

flag - context flag to test

Returns:

true if set, false otherwise.

setContextFlag

protected final void setContextFlag(AbstractInvocationContext.ContextFlag flag)

Utility method that sets a given context flag.

Parameters:

flag - context flag to set

unsetContextFlag

protected final void unsetContextFlag(AbstractInvocationContext.ContextFlag flag)

Utility method that un-sets a context flag.

Parameters:

flag - context flag to unset

setContextFlag

protected final void setContextFlag(AbstractInvocationContext.ContextFlag flag,
                  boolean set)

Utility value that sets or un-sets a context flag based on a boolean passed in

Parameters:

flag - flag to set or unset

set - if true, the context flag is set. If false, the context flag is unset.

getOrigin

public Address getOrigin()

Description copied from interface: InvocationContext

Get the origin of the command, or null if the command originated locally

Specified by:

getOrigin in interface InvocationContext

Returns:

setOrigin

public void setOrigin(Address origin)

hasLockedKey

public boolean hasLockedKey(Object key)

Description copied from interface: InvocationContext

Returns true if the lock being tested is already held in the current scope, false otherwise.

Specified by:

hasLockedKey in interface InvocationContext

Parameters:

key - lock to test

isUseFutureReturnType

public boolean isUseFutureReturnType()

Description copied from interface: InvocationContext

Indicates whether the call requires a Future as return type.

Specified by:

isUseFutureReturnType in interface InvocationContext

Returns:

true if the call requires a Future as return type, false otherwise

setUseFutureReturnType

public void setUseFutureReturnType(boolean useFutureReturnType)

Description copied from interface: InvocationContext

Sets whether the call requires a Future as return type.

Specified by:

setUseFutureReturnType in interface InvocationContext

Parameters:

useFutureReturnType - boolean indicating whether a Future will be needed.

clone

public AbstractInvocationContext clone()

Description copied from interface: InvocationContext

Clones the invocation context.

Specified by:

clone in interface InvocationContext

Overrides:

clone in class Object

Returns:

A cloned instance of this invocation context instance

getClassLoader

public ClassLoader getClassLoader()

Description copied from interface: InvocationContext

Returns the class loader associated with this invocation

Specified by:

getClassLoader in interface InvocationContext

Returns:

a class loader instance or null if no class loader was specifically associated

setClassLoader

public void setClassLoader(ClassLoader classLoader)

Description copied from interface: InvocationContext

Sets the class loader associated for this invocation

Specified by:

setClassLoader in interface InvocationContext

replaceValue

public boolean replaceValue(Object key,
                   InternalCacheEntry cacheEntry)

Description copied from interface: InvocationContext

Tries to replace the value of the wrapped entry associated with the given key in the context, if one exists.

Specified by:

replaceValue in interface InvocationContext

Returns:

true if the context already contained a wrapped entry for which this value was changed, false otherwise.

isEntryRemovedInContext

public boolean isEntryRemovedInContext(Object key)

Specified by:

isEntryRemovedInContext in interface InvocationContext

onEntryValueReplaced

protected void onEntryValueReplaced(Object key,
                        InternalCacheEntry cacheEntry)
