Method Detail

set

public void set(java.lang.Object object)

getFormattedMessage

public java.lang.String getFormattedMessage()

Returns the formatted object message.

Specified by:

getFormattedMessage in interface Message

Returns:

the formatted object message.

formatTo

public void formatTo(java.lang.StringBuilder buffer)

Description copied from interface: StringBuilderFormattable

Writes a text representation of this object into the specified StringBuilder, ideally without allocating temporary objects.

Specified by:

formatTo in interface StringBuilderFormattable

Parameters:

buffer - the StringBuilder to write into

getFormat

public java.lang.String getFormat()

Returns the object formatted using its toString method.

Specified by:

getFormat in interface Message

Returns:

the String representation of the object.

getParameter

public java.lang.Object getParameter()

Returns the object parameter.

Returns:

The object.

Since:

2.7

getParameters

public java.lang.Object[] getParameters()

Returns the object as if it were a parameter.

Specified by:

getParameters in interface Message

Returns:

The object.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getThrowable

public java.lang.Throwable getThrowable()

Gets the message if it is a throwable.

Specified by:

getThrowable in interface Message

Returns:

the message if it is a throwable.

swapParameters

public java.lang.Object[] swapParameters(java.lang.Object[] emptyReplacement)

This message has exactly one parameter (the object), so returns it as the first parameter in the array.

Specified by:

swapParameters in interface ReusableMessage

Parameters:

emptyReplacement - the parameter array to return

Returns:

the specified array

See Also:

ReusableMessage.getParameterCount()

getParameterCount

public short getParameterCount()

This message has exactly one parameter (the object), so always returns one.

Specified by:

getParameterCount in interface ReusableMessage

Returns:

1

forEachParameter

public <S> void forEachParameter(ParameterConsumer<S> action,
                                 S state)

Description copied from interface: ParameterVisitable

Performs the given action for each parameter until all values have been processed or the action throws an exception.

The second parameter lets callers pass in a stateful object to be modified with the key-value pairs, so the TriConsumer implementation itself can be stateless and potentially reusable.

Specified by:

forEachParameter in interface ParameterVisitable

Type Parameters:

S - type of the third parameter

Parameters:

action - The action to be performed for each key-value pair in this collection

state - the object to be passed as the third parameter to each invocation on the specified ParameterConsumer.

memento

public Message memento()

Description copied from interface: ReusableMessage

Returns an immutable snapshot of the current internal state of this reusable message. The returned snapshot will not be affected by subsequent modifications of this reusable message.

Specified by:

memento in interface ReusableMessage

Returns:

an immutable snapshot of this message

clear

public void clear()

Description copied from interface: Clearable

Resets the object to a clean state.

Specified by:

clear in interface Clearable
