Class FileSchema.ElementBuilder

java.lang.Object

dev.hardwood.schema.FileSchema.ElementBuilder

Enclosing class:

FileSchema

public static final class FileSchema.ElementBuilder
extends Object

Declares the element of a LIST, or the value of a MAP: a primitive, a nested struct, a nested LIST, or a nested MAP. The declared node is named element inside a list and value inside a map.

Method Summary

Modifier and Type	Method	Description

Method Details

primitive

public void primitive(PhysicalType type,
 RepetitionType repetition)

Declare a primitive element.

Throws:

IllegalArgumentException - if the type is FIXED_LEN_BYTE_ARRAY (use the type-length overload)

primitive

public void primitive(PhysicalType type,
 RepetitionType repetition,
 int typeLength)

Declare a primitive element, giving the fixed byte length of a FIXED_LEN_BYTE_ARRAY element.

Throws:

IllegalArgumentException - if typeLength does not match the type

primitive

public void primitive(PhysicalType type,
 RepetitionType repetition,
 LogicalType logicalType)

Declare a primitive element carrying a logical type annotation.

Throws:

IllegalArgumentException - if the annotation does not apply to the physical type

primitive

public void primitive(PhysicalType type,
 RepetitionType repetition,
 int typeLength,
 LogicalType logicalType)

Declare a primitive element carrying a logical type annotation, giving the fixed byte length of a FIXED_LEN_BYTE_ARRAY element.

Throws:

IllegalArgumentException - if typeLength does not match the type or the annotation does not apply to it

struct

public void struct(RepetitionType repetition,
 Consumer<FileSchema.StructBuilder> filler)

Declare a struct element.

Throws:

IllegalArgumentException - if the struct has no fields

list

public void list(RepetitionType repetition,
 Consumer<FileSchema.ElementBuilder> element)

Declare a nested LIST element.

map

public void map(RepetitionType repetition,
 PhysicalType keyType,
 Consumer<FileSchema.ElementBuilder> value)

Declare a nested MAP element.

Throws:

IllegalArgumentException - if no value is declared

map

public void map(RepetitionType repetition,
 PhysicalType keyType,
 LogicalType keyLogicalType,
 Consumer<FileSchema.ElementBuilder> value)

Declare a nested MAP element whose key carries a logical type annotation.

Throws:

IllegalArgumentException - if no value is declared or the annotation does not apply to the key's physical type

map

public void map(RepetitionType repetition,
 PhysicalType keyType,
 int keyTypeLength,
 LogicalType keyLogicalType,
 Consumer<FileSchema.ElementBuilder> value)

Declare a nested MAP element whose key carries a logical type annotation, giving the fixed byte length of a FIXED_LEN_BYTE_ARRAY key.

Throws:

IllegalArgumentException - if no value is declared, keyTypeLength does not match the key's type, or the annotation does not apply to it
