MTLInMemoryStrategy

actor MTLInMemoryStrategy

Overview

This strategy accumulates generated text in memory rather than writing to files, making it ideal for unit tests, previews, and scenarios where the generated text needs to be processed programmatically.

Overview

Features:

• No file system access: All output stored in memory

• File simulation: Maintains separate buffers per “file”

• Mode handling: Simulates append mode by concatenating to existing buffer

• Retrieval: Generated files can be accessed via getGeneratedFiles()

Example Usage

let strategy = MTLInMemoryStrategy()

// Generate multiple "files"
let writer1 = try await strategy.createWriter(
    url: "file1.txt",
    mode: .create,
    charset: "UTF-8",
    indentation: MTLIndentation()
)
await writer1.writeLine("Content 1")
try await strategy.finalizeWriter(writer1)

let writer2 = try await strategy.createWriter(
    url: "file2.txt",
    mode: .create,
    charset: "UTF-8",
    indentation: MTLIndentation()
)
await writer2.writeLine("Content 2")
try await strategy.finalizeWriter(writer2)

// Retrieve all generated content
let files = await strategy.getGeneratedFiles()
print(files["file1.txt"])  // "Content 1\n"
print(files["file2.txt"])  // "Content 2\n"
