SimpleByteRange

public SimpleByteRange()

SimpleByteRange

public SimpleByteRange(int capacity)

SimpleByteRange

public SimpleByteRange(byte[] bytes)

Create a new ByteRange over the provided bytes.

参数:

bytes - The array to wrap.

SimpleByteRange

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

Create a new ByteRange over the provided bytes.

参数:

bytes - The array to wrap.

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

length - The length of this range.

方法详细资料

unset

public ByteRange unset()

从接口复制的说明: ByteRange

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

返回:

this

set

public ByteRange set(int capacity)

从接口复制的说明: ByteRange

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

指定者:

set 在接口中 ByteRange

覆盖:

set 在类中 AbstractByteRange

参数:

capacity - the size of a new byte[].

返回:

this

set

public ByteRange set(byte[] bytes)

从接口复制的说明: 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().

指定者:

set 在接口中 ByteRange

覆盖:

set 在类中 AbstractByteRange

参数:

bytes - the array to wrap.

返回:

this

set

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

从接口复制的说明: 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.

指定者:

set 在接口中 ByteRange

覆盖:

set 在类中 AbstractByteRange

参数:

bytes - The array to wrap.

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

length - The length of this range.

返回:

this.

put

public ByteRange put(int index,
            byte val)

从接口复制的说明: ByteRange

Store val at index.

参数:

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

val - the value to store.

返回:

this.

put

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

从接口复制的说明: ByteRange

Store val at index.

参数:

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

val - the value to store.

返回:

this.

put

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

从接口复制的说明: ByteRange

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

参数:

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.

返回:

this.

shallowCopy

public ByteRange shallowCopy()

从接口复制的说明: 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.

返回:

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

shallowCopySubRange

public ByteRange shallowCopySubRange(int innerOffset,
                            int copyLength)

从接口复制的说明: 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.

参数:

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

copyLength - Number of bytes in the clone.

返回:

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

equals

public boolean equals(Object thatObject)

覆盖:

equals 在类中 Object

deepCopy

public ByteRange deepCopy()

从接口复制的说明: ByteRange

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

返回:

Deep copy

putInt

public ByteRange putInt(int index,
               int val)

index - the index in the range where val is stored

val - the value to store

返回:

this

putLong

public ByteRange putLong(int index,
                long val)

val - the value to store

返回:

this

putVLong

public int putVLong(int index,
           long val)
