Constructor Details

SimpleByteRange

public SimpleByteRange()

SimpleByteRange

public SimpleByteRange(int capacity)

SimpleByteRange

public SimpleByteRange(byte[] bytes)

Create a new ByteRange over the provided bytes.

Parameters:

bytes - The array to wrap.

SimpleByteRange

public SimpleByteRange(byte[] bytes,
 int offset,
 int length)

Create a new ByteRange over the provided bytes.

Parameters:

bytes - The array to wrap.

offset - The offset into bytes considered the beginning of this range.

length - The length of this range.

Method Details

unset

public ByteRange unset()

Description copied from interface: ByteRange

Nullifies this ByteRange. That is, it becomes a husk, being a range over no byte[] whatsoever.

Specified by:

unset in interface ByteRange

Specified by:

unset in class AbstractByteRange

Returns:

this

set

public ByteRange set(int capacity)

Description copied from interface: ByteRange

Reuse this ByteRange over a new byte[]. offset is set to 0 and length is set to capacity.

Specified by:

set in interface ByteRange

Overrides:

set in class AbstractByteRange

Parameters:

capacity - the size of a new byte[].

Returns:

this

set

public ByteRange set(byte[] bytes)

Description copied from interface: ByteRange

Reuse this ByteRange over a new byte[]. offset is set to 0 and length is set to bytes.length. A null bytes IS supported, in which case this method will behave equivalently to ByteRange.unset().

Specified by:

set in interface ByteRange

Overrides:

set in class AbstractByteRange

Parameters:

bytes - the array to wrap.

Returns:

this

set

public ByteRange set(byte[] bytes,
 int offset,
 int length)

Description copied from interface: ByteRange

Reuse this ByteRange over a new byte[]. A null bytes IS supported, in which case this method will behave equivalently to ByteRange.unset(), regardless of the values of offset and length.

Specified by:

set in interface ByteRange

Overrides:

set in class AbstractByteRange

Parameters:

bytes - The array to wrap.

offset - The offset into bytes considered the beginning of this range.

length - The length of this range.

Returns:

this.

put

public ByteRange put(int index,
 byte val)

Description copied from interface: ByteRange

Store val at index.

Specified by:

put in interface ByteRange

Specified by:

put in class AbstractByteRange

Parameters:

index - the index in the range where val is stored.

val - the value to store.

Returns:

this.

put

public ByteRange put(int index,
 byte[] val)

Description copied from interface: ByteRange

Store val at index.

Specified by:

put in interface ByteRange

Specified by:

put in class AbstractByteRange

Parameters:

index - the index in the range where val is stored.

val - the value to store.

Returns:

this.

put

public ByteRange put(int index,
 byte[] val,
 int offset,
 int length)

Description copied from interface: ByteRange

Store length bytes from val into this range, starting at index. Bytes from val are copied starting at offset into the range.

Specified by:

put in interface ByteRange

Specified by:

put in class AbstractByteRange

Parameters:

index - position in this range to start the copy.

val - the value to store.

offset - the offset in val from which to start copying.

length - the number of bytes to copy from val.

Returns:

this.

shallowCopy

public ByteRange shallowCopy()

Description copied from interface: ByteRange

Create a new ByteRange that points at this range's byte[]. Modifying the shallowCopy will modify the bytes in this range's array. Pass over the hash code if it is already cached.

Returns:

new ByteRange object referencing this range's byte[].

shallowCopySubRange

public ByteRange shallowCopySubRange(int innerOffset,
 int copyLength)

Description copied from interface: ByteRange

Create a new ByteRange that points at this range's byte[]. The new range can have different values for offset and length, but modifying the shallowCopy will modify the bytes in this range's array. Pass over the hash code if it is already cached.

Parameters:

innerOffset - First byte of clone will be this.offset + copyOffset.

copyLength - Number of bytes in the clone.

Returns:

new ByteRange object referencing this range's byte[].

equals

public boolean equals(Object thatObject)

Overrides:

equals in class Object

deepCopy

public ByteRange deepCopy()

Description copied from interface: ByteRange

Create a new ByteRange with new backing byte[] containing a copy of the content from this range's window.

Returns:

Deep copy

putInt

public ByteRange putInt(int index,
 int val)

Description copied from interface: ByteRange

Store the int value at index

Specified by:

putInt in interface ByteRange

Specified by:

putInt in class AbstractByteRange

Parameters:

index - the index in the range where val is stored

val - the value to store

Returns:

this

putLong

public ByteRange putLong(int index,
 long val)

Description copied from interface: ByteRange

Store the long value at index

Specified by:

putLong in interface ByteRange

Specified by:

putLong in class AbstractByteRange

Parameters:

index - the index in the range where val is stored

Returns:

this

putShort

public ByteRange putShort(int index,
 short val)

Description copied from interface: ByteRange

Store the short value at index

Specified by:

putShort in interface ByteRange

Specified by:

putShort in class AbstractByteRange

Parameters:

index - the index in the range where val is stored

val - the value to store

Returns:

this

putVLong

public int putVLong(int index,

Description copied from interface: ByteRange

Store the long value at index as a VLong

Specified by:

putVLong in interface ByteRange

Specified by:

putVLong in class AbstractByteRange

Parameters:

index - the index in the range where val is stored
