Constructor Detail

IntegerField

public IntegerField(String identity)

IntegerField

public IntegerField(String identity,
                    byte application,
                    short permission)

IntegerField

public IntegerField(String identity,
                    int value)

Construct the field with the value from the native type

Parameters:

identity - the field identity

value - the native value for the field

IntegerField

public IntegerField(String identity,
                    String value)

Construct the field with the value from a string representation of the native type

Parameters:

identity - the field identity

value - the string representation of the value for the field

Method Detail

getLog

protected AsyncLog getLog()

Description copied from class: AbstractLifeCycle

Get the log to use for the object hierarchy

Overrides:

getLog in class AbstractComponent

Returns:

the log to use for the object hierarchy

get

public int get()

Get the integer value of the field

Returns:

the integer value of this field

set

public boolean set(int value)

Set the integer value for the field. If the field value changes, an event is generated.

Parameters:

value - the new integer value for this field

Returns:

true if the value of the field changed

#notifyEvent(fulmine.model.event.IEvent)

doReadState

protected boolean doReadState(IOperationScope scope,
                              byte[] buffer,
                              int start,
                              int numberOfBytes)
                       throws Exception

Description copied from class: AbstractComponent

Update the component state from the wire format state in the buffer. Any nested fields must be read using their AbstractComponent.readState(IOperationScope, byte[], int, int) method.

Specified by:

doReadState in class AbstractComponent

Returns:

true if the read operation succeded.

Throws:

Exception

See Also:

IWireState.readState(IOperationScope, byte[], int, int)

doWriteState

protected boolean doWriteState(IOperationScope scope,
                               IWireIdentity wireId,
                               byte[][] headerBuffer,
                               int[] headerBufferPosition,
                               byte[][] dataBuffer,
                               int[] dataBufferPosition,
                               boolean completeState)
                        throws Exception

Description copied from class: AbstractComponent

Write the component state in its wire form to the buffer. Any nested fields must be written by calling their AbstractComponent.writeState(IOperationScope, IWireIdentity, byte[][], int[], byte[][], int[], boolean) method.

Specified by:

doWriteState in class AbstractComponent

Returns:

true if the write operation succeeded

Throws:

Exception

See Also:

IWireState.writeState(IOperationScope, IWireIdentity, byte[][], int[], byte[][], int[], boolean), for a discussion of the byte[][] usage

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractField

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractField

getValueAsString

public String getValueAsString()

Description copied from interface: IField

Get the value of this field as a string.

Returns:

a string representing the value of this field.

getValue

public Object getValue()

Description copied from interface: IField

Get the field value

Returns:

the field type

setValueFromString

public boolean setValueFromString(String value)

Description copied from interface: IField

Set the field value from the string. The field converts the string into the field's data format. If there is an error performing this, the operation simply returns false or throws a RuntimeException.

Specified by:

setValueFromString in interface IField

Overrides:

setValueFromString in class AbstractField

Parameters:

value - the value to set

Returns:

true if the value changed, false if it did not or there was a problem converting the string to the field's data format
