Class ModelMetadata.Builder

  • Enclosing class:
    ModelMetadata
    public static class ModelMetadata.Builder
extends Object
    Builder for constructing ModelMetadata instances.

    Provides a fluent API for setting metadata attributes with sensible defaults:

    • modelVersion: "unknown"
    • inputSchema: empty map
    • outputSchema: empty map
    • modelSize: 0L
    • loadTimestamp: current system time

    Example:

    
 ModelMetadata metadata = ModelMetadata.builder()
     .modelName("resnet50")
     .format(ModelFormat.ONNX)
     .modelSize(1024 * 1024 * 100) // 100MB
     .build();

      • inputSchema

        public ModelMetadata.Builder inputSchema​(Map<String,​Object> inputSchema)
        Sets the input schema.

        Creates a defensive copy of the provided map.

        Parameters:
        inputSchema - map of input names to schema definitions
        Returns:
        this builder for method chaining

      • outputSchema

        public ModelMetadata.Builder outputSchema​(Map<String,​Object> outputSchema)
        Sets the output schema.

        Creates a defensive copy of the provided map.

        Parameters:
        outputSchema - map of output names to schema definitions
        Returns:
        this builder for method chaining

      • modelSize

        public ModelMetadata.Builder modelSize​(long modelSize)
        Sets the model size in bytes.

        Defaults to 0L if not specified.

        Parameters:
        modelSize - size in bytes
        Returns:
        this builder for method chaining

      • loadTimestamp

        public ModelMetadata.Builder loadTimestamp​(long loadTimestamp)
        Sets the load timestamp.

        Defaults to current system time if not specified.

        Parameters:
        loadTimestamp - timestamp in epoch milliseconds
        Returns:
        this builder for method chaining

      • build

        public ModelMetadata build()
        Builds a new ModelMetadata instance.
        Returns:
        a new immutable ModelMetadata instance
        Throws:
