Package gudusoft.gsqlparser.sqlenv

Class Summary

Class	Description

BucketedIndex	分桶索引（SQL Server COLLATION_BASED 专用）
CanonKey	Canonical identity of a single SQL identifier segment under one vendor's identifier rules (unification plan stage P0c, docs/refactor/identifier_normalization_unification_plan.md).
CatalogStore	Unified storage abstraction for catalog objects using canonical keys.
CatalogStore.QualifiedName	Immutable qualified name used as a canonical key.
CollationCompatView	Collation 兼容视图（将旧布尔常量映射到 IdentifierProfile）
CollatorProvider	Collator 提供者（SQL Server COLLATION_BASED 专用）
CompositeKeyOptimizer	Composite Key Optimizer (Phase 4 - Couchbase 优化)
HierarchicalResolver	Hierarchical Resolver (Phase 2 - 分层索引解析器)
IdentifierCodec	Vendor-aware quote codec for database identifiers (U2a of the persistent canonical-identity program).
IdentifierProfile	厂商标识符配置档案（Vendor Identifier Profile）
IdentifierProfile.Builder	Builder for creating customized IdentifierProfile instances.
IdentifierProfile.VendorFlags	Vendor-specific flags（厂商特定配置）
IdentifierRolePolicy	Maps a component's semantic role to the ESQLDataObjectType whose comparison and quoting rules apply (stage S0R of docs/refactor/identifier_identity_display_separation_plan.md).
IdentifierRules	标识符规则四元组（per vendor, per object group）
IdentifierService	标识符服务（Identifier Service）
NameKey	Canonical key for indexing schema objects.
NameNormalizer	Utility to compute canonical identifier representations based on vendor rules.
NamePolicyFactory	Factory for creating SqlNameMatcher instances per database vendor and object type.
NameService	Vendor-aware and type-aware name comparison utilities over the CANONICAL identifier-equality engine (unification plan P0d follow-up).
PersistentIdentifierKey	Persistable canonical identity of a single identifier segment (plan §6, docs/designs/persistent-canonical-identity-implementation-plan.md).
QualifiedCanonKey	Canonical identity of a possibly-qualified SQL name — db.schema.table, schema.table.column, t.c — for use as a map or set key (stage S0 of docs/refactor/identifier_identity_display_separation_plan.md).
QualifiedName	Value object representing a multi-part qualified name and its canonical form.
QualifiedNameHierarchy	Assigns a per-segment ESQLDataObjectType to the segments of a qualified SQL name (stage S0 of docs/refactor/identifier_identity_display_separation_plan.md).
QualifiedNameHierarchy.Segment	One planned segment: its text exactly as written, plus the kind it is compared as.
SqlNameGenerator	Generates a SQL name from STORED name segments.
SqlNameGenerator.Result	Outcome of a generation: either the SQL text, or the reason there is none.
SqlNameGenerator.Segment	One stored name segment together with its syntactic role.
TDDLSQLEnv
TemporaryTableSemantics	Who can see a temporary table's definition, per vendor and declaration form.
TFunctoinColumn	table function return column
TServerSQLEnv
TSQLCatalog	In the most sql-implementation, Catalog is the anonymous of the Database.
TSQLColumn	table column
TSQLEnv	SQL environment includes the metadata of a list of databases.
TSQLFunction	SQL function
TSQLObject	base class of all the database object such as catalog, schema, table, column and etc
TSQLOraclePackage	SQL procedure
TSQLParameter
TSQLProcedure	SQL procedure
TSQLRoutine
TSQLRoutine.PresetValue	A value set in advance for a parameter of the routine (Mantis 4962): the dynamic SQL evaluation of the routine reads it as the parameter's value, ahead of the routine's call sites, as a caller passing it would.
TSQLSchema	SQL schema, contains a list of schema objects.
TSQLSchemaObject	the base class of all schema objects such as procedure, table, trigger and etc.
TSQLSynonyms	SQL synonyms object.
TSQLTable	SQL table, includes a list of columns.
TSQLTrigger	SQL trigger

Enum Summary

Enum	Description
ESQLDataObjectType	database object type
IdentifierComponentRole	The structural role one component of a qualified SQL name plays — stage S0R of docs/refactor/identifier_identity_display_separation_plan.md.
IdentifierInputForm	How an identifier string reached the caller — the two forms are NOT interchangeable and selecting the wrong one silently produces wrong keys (plan §6, docs/designs/persistent-canonical-identity-implementation-plan.md).
IdentifierProfile.ObjectGroup	对象组（用于区分不同对象类型的标识符规则）
IdentifierRules.CaseCollapse	The mapping under which an INSENSITIVE, non-folding branch compares: two names are one name when their images are equal.
IdentifierRules.CaseCompare	大小写比较规则（Case Comparison）
IdentifierRules.CaseFold	大小写折叠规则（Case Folding）
SqlNameGenerator.Failure	Why a name could not be generated.
SqlNameGenerator.QuotePolicy	How to choose between the bare and the delimited spelling of a segment.
TemporaryTableSemantics.Scope	Who can see a temporary table's definition.
TSQLRoutine.PresetValue.Kind

Exception Summary

Exception	Description
IdentifierCodec.MalformedIdentifierException	Thrown by IdentifierCodec.decodeLexical(gudusoft.gsqlparser.sqlenv.IdentifierProfile, gudusoft.gsqlparser.sqlenv.ESQLDataObjectType, java.lang.String) when the input starts with a recognized open delimiter but is not a well-formed quoted identifier.
IdentifierService.MixedKindProfileException	Typed rejection for mixed-kind custom profiles (one branch collation-based, one fold-based — the cell shape IdentifierService.areEqual(java.lang.String, java.lang.String, gudusoft.gsqlparser.sqlenv.ESQLDataObjectType)'s mixed-payload-kind guard never key-matches).
TSQLEnv.InvalidNameFormException	A metadata file declared a nameForm that cannot be honored: a misspelt value, or CATALOG_STORED on a format whose loader only reads SQL spellings.
