Class FileOperator

java.lang.Object

okhttp3.internal.cache2.FileOperator

final class FileOperator
extends java.lang.Object

Read and write a target file. Unlike Okio's built-in file source and file sink this class offers:

• Read/write: read and write using the same operator.
• Random access: access any position within the file.
• Shared channels: read and write a file channel that's shared between multiple operators. Note that although the underlying FileChannel may be shared, each FileOperator should not be.
