SimpleMutableByteRange

public SimpleMutableByteRange()

Create a new ByteRange lacking a backing array and with an undefined viewport.

SimpleMutableByteRange

public SimpleMutableByteRange(int capacity)

Create a new ByteRange over a new backing array of size capacity. The range's offset and length are 0 and capacity, respectively.

参数:

capacity - the size of the backing array.

SimpleMutableByteRange

public SimpleMutableByteRange(byte[] bytes)

Create a new ByteRange over the provided bytes.

参数:

bytes - The array to wrap.

SimpleMutableByteRange

public SimpleMutableByteRange(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.

指定者:

unset 在接口中 ByteRange

指定者:

unset 在类中 AbstractByteRange

返回:

this

put

public ByteRange put(int index,
                     byte val)

指定者:

put 在接口中 ByteRange

指定者:

put 在类中 AbstractByteRange

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.

指定者:

put 在接口中 ByteRange

指定者:

put 在类中 AbstractByteRange

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.

指定者:

put 在接口中 ByteRange

指定者:

put 在类中 AbstractByteRange

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.

putShort

public ByteRange putShort(int index,
                          short val)

从接口复制的说明: ByteRange

Store the short value at index

指定者:

putShort 在接口中 ByteRange

指定者:

putShort 在类中 AbstractByteRange

参数:

index - the index in the range where val is stored

val - the value to store

返回:

this

putInt

public ByteRange putInt(int index,
                        int val)

Deep copy

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.
