类 AbstractDataBufferDecoder<T>

java.lang.Object
org.springframework.core.codec.AbstractDecoder<T>
org.springframework.core.codec.AbstractDataBufferDecoder<T>
类型参数:
T - the element type
所有已实现的接口:
org.springframework.core.codec.Decoder<T>
public abstract class AbstractDataBufferDecoder<T> extends org.springframework.core.codec.AbstractDecoder<T>
Abstract base class for Decoder implementations that can decode a DataBuffer directly to the target element type.

Sub-classes must implement decodeDataBuffer(org.springframework.core.io.buffer.DataBuffer, org.springframework.core.ResolvableType, org.springframework.util.MimeType, java.util.Map<java.lang.String, java.lang.Object>) to provide a way to transform a DataBuffer to the target data type. The default decode(org.reactivestreams.Publisher<org.springframework.core.io.buffer.DataBuffer>, org.springframework.core.ResolvableType, org.springframework.util.MimeType, java.util.Map<java.lang.String, java.lang.Object>) implementation transforms each individual data buffer while decodeToMono(org.reactivestreams.Publisher<org.springframework.core.io.buffer.DataBuffer>, org.springframework.core.ResolvableType, org.springframework.util.MimeType, java.util.Map<java.lang.String, java.lang.Object>) applies "reduce" and transforms the aggregated buffer.

Sub-classes can override decode(org.reactivestreams.Publisher<org.springframework.core.io.buffer.DataBuffer>, org.springframework.core.ResolvableType, org.springframework.util.MimeType, java.util.Map<java.lang.String, java.lang.Object>) in order to split the input stream along different boundaries (e.g. on new line characters for String) or always reduce to a single data buffer (e.g. Resource).

    • setMaxInMemorySize

      public void setMaxInMemorySize(int byteCount)
      Configure a limit on the number of bytes that can be buffered whenever the input stream needs to be aggregated. This can be a result of decoding to a single DataBuffer, ByteBuffer, byte[], Resource, String, etc. It can also occur when splitting the input stream, e.g. delimited text, in which case the limit applies to data buffered between delimiters.

      By default this is set to 256K.

      参数:
      byteCount - the max number of bytes to buffer, or -1 for unlimited
