public class BinaryBooleanReference
extends AbstractReference
implements net.openhft.chronicle.core.values.BooleanValue

Represents a binary reference to a boolean value.

This class encapsulates a reference to a boolean value stored in binary form. It provides functionality to read and write a boolean value to/from a BytesStore.

Method Detail

bytesStore

public void bytesStore(@NotNull
                       @NotNull BytesStore bytes,
                       long offset,
                       long length)
                throws IllegalStateException,
                       IllegalArgumentException,
                       BufferOverflowException

Sets the underlying BytesStore to work with, along with the offset and length.

Specified by:

bytesStore in interface Byteable

Overrides:

bytesStore in class AbstractReference

Parameters:

bytes - the BytesStore to set

offset - the offset to set

length - the length to set

Throws:

IllegalArgumentException - If the arguments are invalid

BufferOverflowException - If the provided buffer is too small

net.openhft.chronicle.core.io.ClosedIllegalStateException - If the resource has been released or closed.

net.openhft.chronicle.core.io.ThreadingIllegalStateException - If this resource was accessed by multiple threads in an unsafe way

IllegalStateException

maxSize

public long maxSize()

Returns the maximum size of the byte representation of a boolean value.

Specified by:

maxSize in interface Byteable

Returns:

The maximum size of a boolean in bytes

getValue

public boolean getValue()
                 throws IllegalStateException,
                        BufferUnderflowException

Reads a boolean value from the bytes store.

Specified by:

getValue in interface net.openhft.chronicle.core.values.BooleanValue

Returns:

The read boolean value

Throws:

BufferUnderflowException - If the bytes store contains insufficient data

net.openhft.chronicle.core.io.ClosedIllegalStateException - If the resource has been released or closed.

net.openhft.chronicle.core.io.ThreadingIllegalStateException - If this resource was accessed by multiple threads in an unsafe way

IllegalStateException

setValue

public void setValue(boolean flag)
              throws IllegalStateException

Writes a boolean value to the bytes store.

Specified by:

setValue in interface net.openhft.chronicle.core.values.BooleanValue

Parameters:

flag - The boolean value to write

Throws:

net.openhft.chronicle.core.io.ClosedIllegalStateException - If the resource has been released or closed.

net.openhft.chronicle.core.io.ThreadingIllegalStateException - If this resource was accessed by multiple threads in an unsafe way

IllegalStateException
