Class AcDbTextStyleTable

Symbol table for text style table records.

This class manages text style table records which represent text styles within a drawing database. Text styles define the appearance and properties of text entities, including font, size, and other formatting options.

Example

const textStyleTable = new AcDbTextStyleTable(database);
const fonts = textStyleTable.fonts;
console.log('Available fonts:', fonts);

Parameters
- db: AcDbDatabase
  The database this text style table belongs to
Returns AcDbTextStyleTable

Accessors

attrs

get attrs(): AcCmObject<ATTRS>
Gets the attributes object for this AcDbObject.

Returns AcCmObject<ATTRS>
The AcCmObject instance containing all attributes
Example
```
const attrs = obj.attrs;
const value = attrs.get('someAttribute');
```
Inherited from AcDbSymbolTable.attrs
- Defined in data-model/src/base/AcDbObject.ts:80

database

get database(): AcDbDatabase
Gets the database in which this object is resident.

When an object isn't added to a database, this property returns the current working database. After it is added to a database, it will be set automatically. You should never set this value manually.

Returns AcDbDatabase
The database this object belongs to
Example
```
const db = obj.database;
```
Inherited from AcDbSymbolTable.database
- Defined in data-model/src/base/AcDbObject.ts:223
set database(db: AcDbDatabase): void
Sets the database for this object.

This is typically set automatically when the object is added to a database. Manual setting should be avoided unless you know what you're doing.
Parameters
- db: AcDbDatabase
  The database to associate with this object
Returns void
Example
```
obj.database = myDatabase;
```
Inherited from AcDbSymbolTable.database
- Defined in data-model/src/base/AcDbObject.ts:242

fonts

get fonts(): string[]
Gets all fonts used in text styles.

This method iterates through all text style table records and extracts the font names from both the primary font file and big font file. Font names are normalized by removing file extensions and converting to lowercase.

Returns string[]
Array of unique font names used in text styles
Example
```
const fonts = textStyleTable.fonts;
console.log('Available fonts:', fonts);
// Output: ['arial', 'times', 'calibri', ...]
```
- Defined in data-model/src/database/AcDbTextStyleTable.ts:50

objectId

get objectId(): string
Gets the object ID.

AutoCAD uses 64-bit integers to represent handles, which exceed the maximum integer value of JavaScript. Therefore, strings are used to represent object handles.

Returns string
The object ID as a string
Example
```
const id = obj.objectId;
console.log(`Object ID: ${id}`);
```
Inherited from AcDbSymbolTable.objectId
- Defined in data-model/src/base/AcDbObject.ts:163
set objectId(value: string): void
Sets the object ID.
Parameters
- value: string
  The new object ID
Returns void
Example
```
obj.objectId = 'new-object-id';
```
Inherited from AcDbSymbolTable.objectId
- Defined in data-model/src/base/AcDbObject.ts:177

ownerId

get ownerId(): string
Gets the object ID of the owner of this object.

Returns string
The owner object ID
Example
```
const ownerId = obj.ownerId;
```
Inherited from AcDbSymbolTable.ownerId
- Defined in data-model/src/base/AcDbObject.ts:191
set ownerId(value: string): void
Sets the object ID of the owner of this object.
Parameters
- value: string
  The new owner object ID
Returns void
Example
```
obj.ownerId = 'parent-object-id';
```
Inherited from AcDbSymbolTable.ownerId
- Defined in data-model/src/base/AcDbObject.ts:205

Methods

add

add(record: AcDbTextStyleTableRecord): void
Adds a record to both the database containing the table and the table itself.
Parameters
- record: AcDbTextStyleTableRecord
  The record to add to the table
Returns void
Example
```
const record = new AcDbSymbolTableRecord({ name: 'MyRecord' });
symbolTable.add(record);
```
Inherited from AcDbSymbolTable.add
- Defined in data-model/src/database/AcDbSymbolTable.ts:60

close

close(): void
Closes the object.

All changes made to the object since it was opened are committed to the database, and a "closed" notification is sent. This method can be overridden by subclasses to provide specific cleanup behavior.

Returns void
Example
```
obj.close();
```
Inherited from AcDbSymbolTable.close
- Defined in data-model/src/base/AcDbObject.ts:258

getAt

getAt(name: string): undefined | AcDbTextStyleTableRecord
Searches the table for a record with the specified name.
Parameters
- name: string
  The name to search for
Returns undefined | AcDbTextStyleTableRecord
The record with the specified name, or undefined if not found
Example
```
const record = symbolTable.getAt('MyRecord');
if (record) {
  console.log('Found record:', record.name);
}
```
Inherited from AcDbSymbolTable.getAt
- Defined in data-model/src/database/AcDbSymbolTable.ts:176

getAttr

getAttr(attrName: string): any
Gets the value of the specified attribute.

This method will throw an exception if the specified attribute doesn't exist. Use getAttrWithoutException() if you want to handle missing attributes gracefully.
Parameters
- attrName: string
  The name of the attribute to retrieve
Returns any
The value of the specified attribute
Throws
When the specified attribute doesn't exist
Example
```
try {
  const value = obj.getAttr('objectId');
} catch (error) {
  console.error('Attribute not found');
}
```

- Defined in data-model/src/base/AcDbObject.ts:103

getAttrWithoutException

getAttrWithoutException(attrName: string): any
Gets the value of the specified attribute without throwing an exception.

This method returns undefined if the specified attribute doesn't exist, making it safer for optional attributes.
Parameters
- attrName: string
  The name of the attribute to retrieve
Returns any
The value of the specified attribute, or undefined if it doesn't exist
Example
```
const value = obj.getAttrWithoutException('optionalAttribute');

  // Use the value
}
