Method Detail

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface DataAccess

getByte

public byte getByte()

Specified by:

getByte in interface DataAccess

setByte

public void setByte(byte element)

Specified by:

setByte in interface DataAccess

getChar

public char getChar()

Description copied from interface: DataAccess

Relative get method for reading a char value. Reads the next two bytes at this buffer's current position, composing them into a char value according to the current byte order, and then increments the position by two.

Specified by:

getChar in interface DataAccess

Returns:

The char value at the current position

setChar

public void setChar(char element)

Description copied from interface: DataAccess

Relative put method for writing a char value (optional operation). Writes two bytes containing the given char value, in the current byte order, into this buffer at the current position, and then increments the position by two.

Specified by:

setChar in interface DataAccess

Parameters:

element - The char value to be written
