方法详细资料

setInt

public void setInt(int i,
                   int value)

从接口复制的说明: MutableBytes

Set the 4 bytes starting at the specified index to the specified integer value.

指定者:

setInt 在接口中 MutableBytes

参数:

i - The index, which must less than or equal to size() - 4.

value - The integer value.

setLong

public void setLong(int i,
                    long value)

从接口复制的说明: MutableBytes

Set the 8 bytes starting at the specified index to the specified long value.

指定者:

setLong 在接口中 MutableBytes

参数:

i - The index, which must less than or equal to size() - 8.

value - The long value.

set

public void set(int i,
                byte b)

从接口复制的说明: MutableBytes

Set a byte in this value.

指定者:

set 在接口中 MutableBytes

参数:

i - The index of the byte to set.

b - The value to set that byte to.

mutableSlice

public MutableBytes mutableSlice(int i,
                                 int length)

从接口复制的说明: MutableBytes

Create a mutable slice of the bytes of this value.

Note: the resulting slice is only a view over the original value. Holding a reference to the returned slice may hold more memory than the slide represents. Use Bytes.copy() on the returned slice to avoid this.

指定者:

mutableSlice 在接口中 MutableBytes

参数:

i - The start index for the slice.

length - The length of the resulting value.

返回:

A new mutable view over the bytes of this value from index i (included) to index i + length (excluded).

copy

public Bytes copy()

从接口复制的说明: Bytes

Return a value equivalent to this one but guaranteed to 1) be deeply immutable (i.e. the underlying value will be immutable) and 2) to not retain more bytes than exposed by the value.

指定者:

copy 在接口中 Bytes

返回:

A value, equals to this one, but deeply immutable and that doesn't retain any "unreachable" bytes. For performance reasons, this is allowed to return this value however if it already fit those constraints.

size

public int size()

从接口复制的说明: Bytes

Provides the number of bytes this value represents.

返回:

The number of bytes this value represents.

getInt

public int getInt(int i)

从接口复制的说明: Bytes

Retrieve the 4 bytes starting at the provided index in this value as an integer.

参数:

i - The index from which to get the int, which must less than or equal to size() - 4.

返回:

An integer whose value is the 4 bytes from this value starting at index i.

getLong

public long getLong(int i)

从接口复制的说明: Bytes

Retrieves the 8 bytes starting at the provided index in this value as a long.

参数:

i - The index from which to get the long, which must less than or equal to size() - 8.

返回:

A long whose value is the 8 bytes from this value starting at index i.

get

public byte get(int i)

从接口复制的说明: Bytes

Retrieve a byte in this value.

参数:

i - The index of the byte to fetch within the value (0-indexed).

返回:

The byte at index i in this value.

slice

public Bytes slice(int i,
                   int length)

从接口复制的说明: Bytes

Create a new value representing (a view of) a slice of the bytes of this value.

Please note that the resulting slice is only a view and as such maintains a link to the underlying full value. So holding a reference to the returned slice may hold more memory than the slide represents. Use Bytes.copy() on the returned slice if that is not what you want.

参数:

i - The start index for the slice.

length - The length of the resulting value.

返回:

A new value providing a view over the bytes from index i (included) to i + length (excluded).

mutableCopy

public MutableBytes mutableCopy()

从接口复制的说明: Bytes

Return a new mutable value initialized with the content of this value.

返回:

A mutable copy of this value. This will copy bytes, modifying the returned value will not modify this value.

appendTo

public void appendTo(ByteBuffer byteBuffer)

从接口复制的说明: Bytes

Append the bytes of this value to the ByteBuffer.

参数:

byteBuffer - The ByteBuffer to which to append this value.

toArray

public byte[] toArray()

从接口复制的说明: Bytes

Extract the bytes of this value into a byte array.

返回:

A byte array with the same content than this value.

toArrayUnsafe

public byte[] toArrayUnsafe()

从接口复制的说明: Bytes

Get the bytes represented by this value as byte array.

Contrarily to Bytes.toArray(), this may avoid allocating a new array and directly return the backing array of this value if said value is array backed and doing so is possible. As such, modifications to the returned array may or may not impact this value. As such, this method should be used with care and hence the "unsafe" moniker.

返回:

A byte array with the same content than this value, which may or may not be the direct backing of this value.
