Method Detail

values

public static final SnoopBlockRecord.SnoopBlockHeader[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(SnoopBlockRecord.SnoopBlockHeader c : SnoopBlockRecord.SnoopBlockHeader.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static SnoopBlockRecord.SnoopBlockHeader valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

getLength

protected final int getLength()

Returns:

the length of the field

getOffset

public final int getOffset()

Returns:

Returns the offset from the start of the header of the field.

read

public <T> T read()

Reads the header field using the currently set debug buffer buffer. The buffer can not be null otherwise IllegalStateException is thrown.

Specified by:

read in interface Record.RecordHeaderField

Type Parameters:

T - the return type of the field

Returns:

value of the field as read from the debug buffer

read

public <T> T read(java.nio.ByteBuffer buffer)

Gets the field value from the specified buffer using the global buffer offset of 0.

Specified by:

read in interface Record.RecordHeaderField

Type Parameters:

T - field's value type

Parameters:

buffer - buffer to read the field's value from

Returns:

field value as read from the supplied buffer

read

public <T> T read(java.nio.ByteBuffer buffer,
                  int start)

Gets the field value from the specified buffer using the global buffer offset start.

Specified by:

read in interface Record.RecordHeaderField

Type Parameters:

T - field's value type

Parameters:

buffer - buffer to read the field's value from

start - start or offset within the buffer to offset the field's value read

Returns:

field value as read from the supplied buffer

toStringDebug

public java.lang.String toStringDebug()

Returns a special debug string for the field. The returned string contains the name of the field, the field's offset within the header, the length in bits of the field and lastly uses the debug buffer with global offset of 0 to read a a value. Therefore the debug buffer must be initialized to a buffer before this method is invoked.

Specified by:

toStringDebug in interface Record.RecordHeaderField

Returns:

specially formatted string for debug output

write

public <T> void write(java.nio.ByteBuffer buffer,
                      int start,
                      T value)

Writes the field value from the specified buffer using the global buffer offset of start.

Specified by:

write in interface Record.RecordHeaderField

Type Parameters:

T - field's value type

Parameters:

buffer - buffer to write the field's value to

start - the global offset within the buffer that marks the start of the header

value - the new vlue of the field

write

public <T> void write(java.nio.ByteBuffer buffer,
                      T value)

Writes the field value from the specified buffer using the global buffer offset of 0.

Specified by:

write in interface Record.RecordHeaderField

Type Parameters:

T - field's value type

Parameters:

buffer - buffer to write the field's value to

value - the new vlue of the field

write

public <T> void write(T value)

Writes the header field using the currently set debug buffer buffer. The buffer can not be null otherwise IllegalStateException is thrown.

Specified by:

write in interface Record.RecordHeaderField

Type Parameters:

T - the value type of the field

Parameters:

value - the new value of the field
