Constructor Details

MemoryLimitsAwareOutputStream

public MemoryLimitsAwareOutputStream()

Creates a new byte array output stream. The buffer capacity is initially 32 bytes, though its size increases if necessary.

MemoryLimitsAwareOutputStream

public MemoryLimitsAwareOutputStream(int size)

Creates a new byte array output stream, with a buffer capacity of the specified size, in bytes.

Parameters:

size - the initial size.

Throws:

IllegalArgumentException - if size is negative.

Method Details

getMaxStreamSize

public long getMaxStreamSize()

Gets the maximum size which can be occupied by this output stream.

Returns:

the maximum size which can be occupied by this output stream.

setMaxStreamSize

public MemoryLimitsAwareOutputStream setMaxStreamSize(int maxStreamSize)

Sets the maximum size which can be occupied by this output stream.

Parameters:

maxStreamSize - the maximum size which can be occupied by this output stream.

Returns:

this MemoryLimitsAwareOutputStream

write

public void write(byte[] b,
 int off,
 int len)

Overrides:
