构造器详细资料

ByteArrayResource

public ByteArrayResource(byte[] byteArray)

Create a new ByteArrayResource.

参数:

byteArray - the byte array to wrap

ByteArrayResource

public ByteArrayResource(byte[] byteArray,
                         @Nullable
                         String description)

Create a new ByteArrayResource with a description.

参数:

byteArray - the byte array to wrap

description - where the byte array comes from

方法详细资料

getRealResource

public byte[] getRealResource()

getByteArray

public final byte[] getByteArray()

Return the underlying byte array.

exists

public boolean exists()

This implementation always returns true.

指定者:

exists 在接口中 Resource<byte[]>

覆盖:

exists 在类中 AbstractResource<byte[]>

contentLength

public long contentLength()

This implementation returns the length of the underlying byte array.

getInputStream

public InputStream getInputStream()
                           throws IOException

This implementation returns a ByteArrayInputStream for the underlying byte array.

返回:

the input stream for the underlying resource (must not be null)

抛出:

FileNotFoundException - if the underlying resource doesn't exist

IOException - if the content stream could not be opened

ByteArrayInputStream

toString

public String toString()

This implementation returns a description that includes the passed-in description, if any.

覆盖:

toString 在类中 Object

equals

public boolean equals(Object other)

This implementation compares the underlying byte array.

覆盖:

equals 在类中 Object

另请参阅:

Arrays.equals(byte[], byte[])

hashCode

public int hashCode()

This implementation returns the hash code based on the underlying byte array.

覆盖:

hashCode 在类中 Object
